Beyond sentiment: knowledge graph-driven financial market forecasting with large language models-extracted enterprise relations and adaptive residual networks

International Journal of Data Science and Analytics2026-03-02Paper
Executive summary

Researchers have developed a new method for financial market forecasting by combining knowledge graphs, large language models, and adaptive deep learning. Their system, using T5-Relation-Aware Attention and BiLSTM with Attention and Layer-wise Residual Connections, improved sentiment classification F1-score by 16 percent and achieved an R² of 0.9695 and RMSE of 2.0861 in stock prediction. The lightweight knowledge graph schema enables efficient automation, but the model’s testing on only nine stocks limits generalizability.

What it examines

This paper introduces a new method for predicting financial markets by combining knowledge graphs, large language models, technical indicators, and deep learning. It aims to improve forecasting by capturing dynamic relationships between companies and integrating sentiment analysis from news, addressing limitations of traditional approaches.

What it concludes

The proposed model achieves higher accuracy in stock price prediction and sentiment classification, reducing errors and improving trend detection. Its practical applications include trading simulations and market analysis. The approach enables adaptive, low-cost knowledge graph construction and suggests future research in expanding generalization across markets and high-frequency trading scenarios.
